Jessica wanted to know how much farther she ran in Week 2 than in Week 1. Her work is below.
15.05 minus 11.90 = 5.95. The decimals in the equation are all aligned. The 0 in 15.05 is crossed out and a 10 is above it. The first 5 in 15.05 is crossed out and a 6 is above it.
What mistakes did Jessica make when solving the problem? Select all that apply.
She did not align the decimal points.
She did not subtract 10 and 9 correctly.
She subtracted instead of adding.
She did not rename correctly.
